            Bug ID: 96804
           Summary: No documentation for module-filter-heuristics and
                    module-filter-apply
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: minor
          Priority: medium
         Component: modules

This is the only documentation about `module-filter-heuristics` and
`module-filter-apply`:

### Modules to allow autoloading of filters (such as echo cancellation)
### on demand. module-filter-heuristics tries to determine what filters
### make sense, and module-filter-apply does the heavy-lifting of
### loading modules and rerouting streams.

By reading these lines, I still have no idea what these filters actually do,
and why both are required to operate.

That's not enough for me, I want to know /exactly/ what these filters do. I can
read the code, but I shouldn't have to. If you look online, the first thing
everybody suggests is to disable these modules as nobody knows what they are
supposed to do and in which conditions.

Please document the exact behavior.
Thanks.
